PRODUCT DESCRIPTION:
The Indelac Controls Electric Fail-Safe Device provides battery backup power to your actuator in the
unlikely event that the Factory or Facility Mains Power should go down. These devices are designed to
seamlessly convert 12vdc, 24vdc or 36vdc battery standby power to 115vac or 230vac to power your
actuator. The battery power supplies an internal Power Inverter that converts the DC to AC to run the
actuator to the user wired Fail Position when the Mains Power fails. When normal Mains Power is present,
it powers the actuator and provides a maintenance charge to the backup battery. When the Mains Power
fails or drops out momentarily, the Power Inverter will automatically switch over to battery power and
supply a PWM sine wave AC to the actuator. When the Mains Power comes back online, the Power
Inverter will immediately transfer Mains Power back to the actuator and proceed to re-charge and maintain
the battery.
The Electric Fail-Safe Devices come in a variety of styles and sizes to fit the smallest to largest of
actuators. Indelac provides these Devices in NEMA 4, NEMA 4X or NEMA 7 enclosures to provide 5, 7,
10, 15 or 30 Amps of output power. Each Fail-Safe Device is designed to supply the actuator’s continuous
Full Load Ampere draw to drive the Actuator to the Fail-Safe position. The Power Inverter can also supply
the additional current required for start-up / Locked Rotor Ampere Torque for up to the initial 1-2 second
turn on.
The internal Power Inverter has a built in 3 Stage Battery Charger for the on-board Sealed Lead Acid
Battery. Depending on the size & age of the battery used in each Fail-Safe Device, battery charge time
can vary from hours to overnight for a full charge.
Optional features, such as Emergency Disconnect Switches, Internal Heaters and Internal Relays to run
more than 1 actuator to Fail Position may be ordered –Consult the Factory for available SPECIAL
Options.

FAIL-SAFE SET-UP & OPERATION:
SET-UP:
When the Fail-Safe Device is mounted and all wiring has been completed to the proper wiring diagram, the
final Set-Up steps can be completed. The Fail-Safe unit is internally wired and ready to be enabled.
1) If the front panel door to the Fail-Safe Device is not open, open it using a flat head screwdriver to
unlock the door latch. On the NEMA 7 Device, you will need to remove ALL of the outer door bolts
to open the door!
2) Check all wiring connections again and verify that all wiring and terminals are tight.
3) Enable the Power Inverter by switching the slide switch on the rear of the unit to the
“AUTO/REMOTE” or Left position. This will involve sliding the switch towards the battery Status
LEDs.
5 Amp Rear Panel View 7 –30 Amp Rear Panel View
4) Once the Power Inverter is in the “AUTO” mode, the Inverter will turn ON and the battery will
power the Inverter to supply 120vac to the Output Terminal Block. CAUTION: Depending on the
position of the Actuator when the set-up was completed, it may start to move.
5) Apply Incoming Mains Power to the Fail-Safe Device and turn ON the front panel Power Switch.
CAUTION: This will apply Mains Power to the Actuator and depending on the position of the
Actuator, it may move again.
6) When the Front Door Power Switch is turned ON, the Front Door Power Switch should illuminate
Red, the Green POWER Light should turn ON to indicate that the Fail-Safe Device is Enabled.
7) Close and Latch (or Bolt) the Front Door securely Closed.
CAUTION: WHEN ENABLING THE POWER INVERTER AND APPLYING
MAINS POWER TO THE FAIL-SAFE DEVICE, LIVE VOLTAGE IS PRESENT!
TAKE GREAT CARE NOT TO TOUCH THE POWER TERMINAS - SERIOUS
INJURY OR DEATH MAY OCCUR!

Electric Fail-Safe Device Installation, Operation & Maintenance Manual
Page 17
OPERATION:
When the Fail-Safe Device is in the Normal Mode, the Red Front Door Power Switch will be illuminated
Red and the Green POWER Light will be ON for the NEMA 4 & NEMA 4X. On the NEMA 7 Version,
there will NOT be a Red Light on the ON/OFF Switch. If the Green POWER Light turns OFF, there is a
blown output fuse and the actuator will not run.
NEMA 4 & 4X NEMA 7
The Fail-Safe Device is designed so that when the Mains Power Fails, or the Front Door Power Switch is
turned OFF, the Red Power Switch Light and Green POWER Light will turn OFF and the Yellow
BATTERY Light will turn ON. This indicates to the User that the Fail-Safe Device is running on Battery
Power and should deliver Power to the User selected Fail Terminal on the Actuator and the Actuator will
drive to that position. This power transfer takes only milliseconds and happens automatically without any
User interface.
When the Mains Power returns, the Fail-Safe Device will automatically switch the Battery power OFF and
enable Mains Power back to the Actuator. When this happens, the Yellow BATTERY Light will turn OFF
and the Green POWER Light and Red Switch Light will both turn back ON. At this time, the battery will
be re-charged by the internal battery charger.
If the Green POWER Light does NOT turn ON, but the Mains Power has been checked and is good to the
Fail-Safe Device, it is possible that the internal Output Fuse has blown. See the Maintenance Section for
how to check this fuse.
If the Mains Power has shut down and the Yellow BATTERY Light does not come ON and there is NO AC
Power to the Actuator, the internal Battery Fuse or Output Fuse may have blown or the Power Inverter was
damaged. See the Maintenance Section for how to check these devices.

BATTERY RUN TIMES:
Each of the Fail-Safe Devices has a minimal run time depending on the load and charge of the battery.
These Devices are calculated to have a continuous battery run time of 8 to 12 minutes under full capacity
load. For example, a 5 Amp Device will run under battery power for 9 minutes under a 5 Amp continuous
load draw. Therefore, if the load draw is less than the Device’s current rating, the battery run time will be
longer. The Fail-Safe Device is designed to run the Actuator to the wired FAIL position and hold there until
Mains Power comes back ON. All of the Indelac Actuators will complete an OPEN or CLOSE cycle in less
than the 8 to 12 minutes under full load with a fully charged battery.
If longer battery run times are required, contact Indelac Controls for special order Fail-Safe Designs.
MAINTENANCE:
After proper installation, the Fail-Safe Device requires no actual maintenance. This unit should operate for
4-5 years on the original battery as long as the Mains Power is applied and the power is ON to maintain the
internal battery charger. However, we do recommend a periodic battery check to assure that the battery is
retaining a charge. This can be accomplished by checking the battery LED indicators on the back panel of
the Power Inverter (see diagrams in Set-Up Section). The left-most column of LEDs gives the charge status
of the battery/battery pack. If the Green Battery Charge LED is lit, battery charge is at FULL. If the
Yellow, Red or NO LEDs are lit, the battery is less than 70-80% and should be charged or replaced.

The Fail-Safe Device can be stored for 4-6 months in the “no load” condition before the battery will need to
be recharged. If these Units are stored longer than this before being installed, the customer needs to
implement a program to charge these batteries for 8-10 hours every 4 months. This will maintain the
batteries until installation. If these batteries are NOT maintained, they will be too low or dead and not
operate when installed.
If the Fail-Safe Device is installed and the Power Inverter Selector Switch in AUTO/REMOTE position, the
Mains Power needs to be turned ON to maintain the battery. The internal trickle charger will maintain the
battery for use when needed. If the Mains Power is shut OFF or the Mains Power Breaker has tripped, the
Fail-Safe will be operating under battery power an illuminates the Front Door Yellow Light. This will drain
the battery more quickly.
To charge a low battery, slide the Power Inverter Selector Switch to CHARGE position and make sure the
Mains Power and Front Door Power Switch is ON. Once the battery charge measures below 6-7vdc, it may
not take a charge due to internal cell damage. Even if the battery does take a charge, it may be unreliable
and SHOULD be REPLACED!
BATTERY MAINTENANCE LOG
ATTENTION: IF THE BATTERY IS NOT PROPERLY MAINTAINED,
THE BATTERY WILL BE TOO LOW TO DRIVE THE ACTUATOR TO
THE FAIL POSITION WHEN NEEDED!
